FIELD OF THE INVENTION [0003] The present invention relates to a hair cleansing and conditioning shampoo containing the combination of a non-guar galactomannan polymer derivative and a gel network comprising a fatty amphiphile. BACKGROUND OF THE INVENTION [0004] Human hair becomes soiled due to its contact with the surrounding environment and from the sebum secreted by the scalp. The soiling of hair causes it to have a dirty feel and an unattractive appearance. The soiling of the hair necessitates shampooing with frequent regularity. [0005] Shampooing cleans the hair by removing excess soil and sebum. However, shampooing can leave the hair in a wet, tangled, and generally unmanageable state. Once the hair dries, it is often left in a dry, rough, lusterless, or frizzy condition due to removal of the hair's natural oils and other natural conditioning and moisturizing components. The hair can further be left with increased levels of static upon drying, which can interfere with combing and result in a condition commonly referred to as "fly-away hair." [0006] A variety of approaches have been developed to alleviate these after-shampoo problems. These approaches range from post-shampoo application of hair conditioners such as leave-on and rinse-off products, to hair conditioning shampoos which attempt to both cleanse and condition the hair from a single product. [0007] Coacervate formation in a shampoo composition is known to be advantageous for providing conditioning benefits to the hair. The use of cationic polymers to form coacervate is known in the art, such as in PCT publications WO 93/08787 and WO 95/01152. Commonly used cationic deposition polymers include natural polymers, such as guar gum polymers that have been modified with cationic substituents. Guar gum polymers are galactomannans containing two mannose monomers with a glycoside linkage and one galactose monomer attached to a hydroxyl group of the mannose monomers (i.e., guar gum polymers have a mannose to galactose ratio of 2:1). The selection of a cationic guar deposition polymer with sufficient charge density and molecular weight results in sufficient deposition of conditioning agents. [0008] However, to achieve this sufficient deposition of conditioning agents in shampoo or body wash compositions using a cationic guar polymer, a relatively high level of such cationic guar polymer generally must be deposited on the hair or skin. Moreover, the cost of such cationic guar polymer is relatively high. As a result, incorporation of cationic guar polymer can add to the manufacturing costs of such shampoo compositions. Additionally, these shampoo compositions typically are good for delivering wet hair conditioning, but are not capable of delivering satisfactory dry hair smooth feel. [0009] Based on the foregoing, there is a need for a conditioning shampoo which can provide improved conditioning benefit for dry hair, while not interfering with the cleansing efficacy, nor providing negative feel to the hair when it is dried. Specifically, there is a need to provide long lasting moisturized feel, smooth feel, and manageability control to the hair when the hair is dried, yet not leave the hair feeling greasy, as well as to provide softness and ease of combing when the hair is wet. SUMMARY OF THE INVENTION [0010] The present invention is directed to a shampoo composition comprising: (a) from about 5% to about 50% of one or more detersive surfactants, by weight of the shampoo composition; (b) a dispersed gel network phase comprising: (i) at least about 0.05% of one or more fatty amphiphiles, by weight of the shampoo composition; (ii) at least about 0.01% of one or more secondary surfactants, by weight of the shampoo composition; and (iii) water; (c) at least about 0.05%, by weight of the shampoo composition, of a galactomannan polymer derivative with a net positive charge and having a mannose to galactose ratio of greater than 2:1 on a monomer to monomer basis, wherein the galactomannan polymer derivative has: (i) a molecular weight from about 1,000 to about 10,000,000; and (ii) a cationic charge density from about 0.7 meq/g to about 7 meq/g; and (d) at least about 20% of an aqueous carrier, by weight of the shampoo composition. [0011] The present invention is further directed to a method of using the shampoo composition described above. [0012] These and other features, aspects, and advantages of the present invention will become evident to those skilled in the art from a reading of the present disclosure. DETAILED DESCRIPTION OF THE INVENTION [0013] While the specification concludes with claims which particularly point out and distinctly claim the invention, it is believed the present invention will be better understood from the following description. [0014] All percentages, parts and ratios are based upon the total weight of the compositions of the present invention, unless otherwise specified. All such weights as they pertain to listed ingredients are based on the active level and, therefore, do not include solvents or by-products that may be included in commercially available materials, unless otherwise specified. The term "weight percent" may be denoted as "wt. %" herein. [0015] All molecular weights as used herein are weight average molecular weights expressed as grams/mole, unless otherwise specified. [0016] The term "charge density", as used herein, refers to the ratio of the number of positive charges on a polymer to the molecular weight of said polymer. [0017] Herein, "comprising" means that other steps and other ingredients which do not affect the end result can be added. This term encompasses the terms "consisting of" and "consisting essentially of". The compositions and methods/processes of the present invention can comprise, consist of, and consist essentially of the essential elements and limitations of the invention described herein, as well as any of the additional or optional ingredients, components, steps, or limitations described herein. [0018] The term "polymer" as used herein shall include materials whether made by polymerization of one type of monomer or made by two (i.e., copolymers) or more types of monomers. [0019] The term "shampoo" as used herein means a composition for cleansing and conditioning hair or skin, including scalp, face, and body.
